When you say you’ll have enough money in your retirement plans to pay for school, do you mean pull from retirement to pay for flight training? Don’t do that if it’s what you mean. Horrendous idea. If you have 8 years left, take a discovery flight and see if you like it. Prior to that get a first class medical. Then start chipping away at it and have your CFI by 4 years from now and then part time instruct for 4 years to build the necessary hours while getting paid for it. Pay cash as you go and let the process take 8 years.
